Whisperity 3b677b81ce [libtooling][clang-tidy] Fix diagnostics not highlighting fed SourceRanges
Fixes bug http://bugs.llvm.org/show_bug.cgi?id=49000.

This patch allows Clang-Tidy checks to do

    diag(X->getLocation(), "text") << Y->getSourceRange();

and get the highlight of `Y` as expected:

    warning: text [blah-blah]
        xxx(something)
        ^   ~~~~~~~~~

Yitzhak Mandelbaum fdff677a95 [libTooling] Remove deprecated Clang Transformer declarations
A number of declarations were leftover after the move from `clang::tooling` to
`clang::transformer`. This patch removes those declarations and upgrades the
handful of references to the deprecated declarations.

Yitzhak Mandelbaum 88e6208562 [libTooling] Update Transformer's `node` combinator to include the trailing semicolon for decls.
Currently, `node` only includes the semicolon for (some) statements. However,
declarations have the same issue of (potentially) trailing semicolons, so `node`
should behave the same for them.

Yitzhak Mandelbaum c5b1a03525 [clang-tidy] In TransformerClangTidyCheck, support option IncludeStyle.
Summary:
The new option allows the user to specify which file naming convention is used
by the source code ('llvm' or 'google').

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Yitzhak Mandelbaum fbdf83521b [libTooling] Move Transformer files to their own directory/library.
Summary:
The Transformer library has been growing inside of
lib/Tooling/Refactoring. However, it's not really related to anything else in
that directory. This revision moves all Transformer-related files into their own
include & lib directories.  A followup revision will (temporarily) add
forwarding headers to help any users migrate their code to the new location.

Yitzhak Mandelbaum 0cd4ab91ab [clang-tidy][NFC] Qualify `makeRule` call in test, for consistency with other calls.
One call `makeRule` is unqualified (and unintentionally relying on ADL to
resolve correctly). This revision qualifies that call for consistency and to
drop use of ADL.

Yitzhak Mandelbaum 640230cc97 [clang-tidy] TransformerClangTidyCheck: change choice of location for diagnostic message.
Summary:
This patch changes the location specified to the
`ClangTidyCheck::diag()`. Currently, the beginning of the matched range is
used. This patch uses the beginning of the first fix's range.  This change both
simplifies the code and (hopefully) gives a more intuitive result: the reported
location aligns with the fix(es) provided, rather than the (arbitrary) range of
the rule's match.

N.B. this patch will break the line offset numbers in lit tests if the first fix
is not at the beginning of the match.

Summary:
This revision implements support for the `AddedIncludes` field in
RewriteRule cases; that is, it supports specifying the addition of include
directives in files modified by the clang tidy check.

Yitzhak Mandelbaum 039af0ea03 [clang-tidy] Generalize TransformerClangTidyCheck to take a rule generator.
Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

Yitzhak Mandelbaum 5b33554319 [clang-tidy] In TransformerClangTidyCheck, require Explanation field.
Summary:
In general, the `Explanation` field is optional in `RewriteRule` cases. But,
because the primary purpose of clang-tidy checks is to provide users with
diagnostics, we assume that a missing explanation is a bug.  This change adds an
assertion that checks all cases for an explanation, and updates the code to rely
on that assertion correspondingly.

Yitzhak Mandelbaum 9df7ce596b [clang-tidy] Add support for writing a check as a Transformer rewrite rule.
This revision introduces an adaptor from Transformer's rewrite rules
(`clang::tooling::RewriteRule`) to `ClangTidyCheck`.  For example, given a
RewriteRule `MyCheckAsRewriteRule`, it lets one define a tidy check as follows:

```
class MyTidyCheck : public TransformerClangTidyCheck {
 public:
  MyTidyCheck(StringRef Name, ClangTidyContext *Context)
      : TransformerClangTidyCheck(MyCheckAsRewriteRule, Name, Context) {}
};
```
